AUTOMQBILErTURN-TABLE.

To all whom iii-may concern:

and useful Improvements; in Automobile- Turntables, of" which the following; IS" a specification;

My inventionrelates to automobile-turn tables of the traveling type, and particularly to devicesof this type which comprise a base, memberhav-ing mobility wheels-and a turret mounted? to rotate on" thebase; and

provided with means for supporting; an au+ t0mob1le.- a I One Ob ect of; my 1nvent1on-1s a'novel construction of the" base: and turret? to permit" of ready" access to thebearings and} at thesame time to prevent tilting of the turret with respect to thebase. i

I Will describe one, form of H1111 table embodying my invention, and will-' thenpoint out the novel features thereof in claims.

In the accompanying drawings, Figure 1" is a top plan View of. a turntable-embody ing'my-invention; F ig.- Qis-aside elevation of the turn-table shownin' Fig. 1. Fig. 3 is a plan View of one half of the base and turret, a portion of the turret being broken away to expose part of the base to view. Fig. 4 is a transverse vertical section of the turn table on the line IV-IV of Fig. 3. looking in the direction indicated by the arrows.

Similar reference characters refer to similar parts in each of the several views.

Referring now to the drawin s, the turn table comprises a base 10, whic in general is shaped like a ring, but which is provided with four ofl'set portions 10" in each of which is journaled a 'mobility wheel 11. These wheels project a slight distance below the under surface of the base, and as is well understood, they are adapted to effect the mobility of the turn table as a whole along a suitable track, or, if desired, along a plane surface, such as the floor of a garage.

The upper surface of the base 10 is provided with a horizontal and circular track or race 12, which serves to support the turret as I will explain hereinafter. The turret, which is designated as a whole by the reference character 13, is ring-shaped and comprises a horizontally disposed portion 13 located directly above the track 12, and a Specificationofletters Patent.

vertically disposed flan e-13?: 13"proj'ects downwardly and is of; such size/as to fitwith'in the mainportion of the base- 10 w-ith ample clearance to insure freedom of rotation [of the turret" with respect to the base. The horizontal" portion; 13" is provided with a plurality of rectangular apertures '15 iir each of-"whi ch .i sjournaled a roller 14." These rollers project below the under surface of the horizontal portion-13; and are arranged to rid e on, the tra ck 12 PatentedJuneY, 192i. Application filed 0ctobe1'r15, 1920.; Seria1"1qjo. 417;074;.

The flange thereby providingrforsupport of" the turreton'thebase and at the same'time permitting the -turretto revolve on the base with minimum --friotion'.=

J eumaled at intervals in the vertically disposed flange 13 are a seriesyof"beveled'."

rollers 16 which a-re arra-nged to -coact with a beveled track; 17 whichis provided on the inner surfaceof the, base- 10. Each roller 16; it will" be observed, is mounted to rotate 011 a horizontal axis. These rolls ers: serve to keep; theptu rret properly centered with-respect to the base, andjtliey also serve to prevent tilting of the turret with respect to the base, both functions being ac:

complished with minimum friction and so with practicallyno resistance to the-rotation of the turret on the base.

As here shown, the upper surface of the base 10 is provided with an upstanding circular flange 10 at the outer edge of the track 12, which flange serves to keep forei n matter away from the track 12 and the re lers 14.

Attached to the turret 13 are two automobile carriers 18, 18, each of which, as here shown, is in the form of an angle bar comprising two horizontal members 18" and 18 connected by a vertical web 18. The horizontal member 18 rests on the top of the turret 13 and is attached thereto by bolts, while the horizontal member 18 lies close to the floor and constitutes a support for the wheel of an automobile. The two carriers 18 are disposed on opposite sides of the turret, and are parallel as shown in Fig. 1. The spacing of these carriers and the length of the same are such as to accommodate the four wheels of an automobile.

To provide the proper rigidity, the two carriers are preferably connected by two channel bars 19, 19 adjacent to the turret, and by two angle bars 20, 20 at the opposite ends of the structure.

The manner in which turn tables of the type described are used in garages and other automobile repositories is so well understood that no further explanation is required herein. I desire to point out, however, that the device which I have described is simple in construction, and that it provides for access to the operating parts without disturb ing any part of the structure.

Although I have herein shown and describe only one form of turn table embodying my invention, it is understood that various changes and 1 modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention. 7

Having thus described my invention, what I claim is:

l. A traveling automobile turn table comprising a base provided with mobility wheels and having a vertical circular aperture, a turret located above said base and having a circular depending flange passing through the aperture in said base, rollerslocated between said base and said turret, other rollers ingtilting of the turret with respect to said base. r

3. A traveling automobile turn table comprising a ring-shaped base provided with mobility wheels, a ring-shaped turret having a flange projecting downwardly into said base, rollers located between said base and said turret for revolubly supporting the turret on the base, and other rollers located between said base and said turret for centering the turret with respect to the base.

4:. A traveling automobile turn table comprising a ring-shaped base provided with mobility wheels, a ring-shaped turret having a flange projecting downwardly into said base, rollers located between said base and said turret for revolubly supporting the turret on the base, and other rollers'located between said base and said turret for preventing tilting of the turret with respect to the base and centering the turret with respect to the base.

5. A traveling automobile turn table com-v prising a ring-shaped base provided 'with mobility wheels, a ring-shaped turret having a flangeproj ecting downwardly into saidbase, rollers located between said base-and said turret for revolubly supporting the tur- .ret on the base, and beveled rollers mounted on horizontal axes in said flange and coop-- erating with a beveledtrack on'saidbase.

6. A traveling automobile turn table comprising telescoping base and turret members, rollers interposed between said members for revolubly mounting the turret on the base, and other rollers interposed between said members for centering the turret With respect to the base.

In testimony whereof I aflix my signature. RICHARD B,. ISEMAN.
